' To a/ZZ whom it may concer-n:

matic tu'be is su jected to no other strain" Be it known that I, FRANK E. NnwcoMB, a citizen of the United States, residing at Cleveland, in the county of Cuyahogaand State of Ohio, have 'nvented new and useful Im rovements in Ve 'cle-Tires, of which. the

f ol owing is a specification.

This invention relates to vehicleitires, and

is particularly adapted for use on motor or traction vehicles in which .the wheels take vthe driving strain. l

' The object of the invention is to provide a Wheel withk a pneumatic or cushion tire c overed by a metal rim which acts as armor for the tire and also relieves thel same' of the tangential or drivin strain, so that the pneuthan that due to the Weight of the vehicle and the nature of the road. The connection between the rim and the wheel isa yielding one, so that the driving, starting, or stopping strains on the Wheels are cushioned to some extent. 1 The inrlention is .-illusltlralted in the accoman a\ s,1nwc-. P Firmge 1 isrlhlg side elevation of the Wheel, and ig. 2 is a section on the line 2 2 of Fig. 1.

Referring specifically to the drawings, 6 indicates the s okes of the wheel, joined to a felly 7, whic shown in the sectional view, and receives the pneumatic tube 8. `Asolidrubber tire may substantially semicircular in cross-section,

being convex on the outside and concave on the inside to fit over thel tube 8, and it ex tends'inwardlyon each s'de'or edge of the felly 7, the contact with t e edges of the rim lbeing a sliding one, so that a yieldin radial movement" is permitted. At interva s, preff erably every second spoke, the rim hasV a pair of inwardly-projecting lugs` 10 on each side,

the radial slots or spaces l1 between the lugs .being of pro er size and shape vto receive metal s rlngars 12, which'i'are clamped to the spo es b. clips 13 and bolts 14, and the opposite en s of which extend a sufficient dlstan'ce to roject in to the slots on the opposite sideso the tire. These springs are sufciently stout to stand the strain, but will nevertheless yield to accommodate sudden is channeled or concave, as

Any side pressure is transmitted directlyV from the rim 9 to the felly 7. The tangen tial or driving strain is transmitted from'the spokes throuo'h the springs 12 to the rim-sec'- tlons. The s ots 11 allow therim-sections toyield inwardlyl to the extent due to the wei ht of the vehicle and to shockyilldent yto o structions in the road, so that the resilient action of the tube 8 is not interfered with.

The tire or tube is held in place by its infv closure Within the rim and 1s not fastened thereto.' The driving strain is not transmitted through the tube, but is transmitted directly from the wheel center to the rim.

There is no wear on the rubber such as that ordinarily due to its contact with the road,

and the rim forms an armor which renders the' tube puncture-proof. There is therefore the advantage of a resilient or pneumatic tire which is made puncture-proof Without any .diminutionof its resiliency, since` the spring'l?J allows the rim to yield when the tube 8 is compressed thereunder; also, the advantage of a more positive drive than that afforded by the contact of rubber with the road or pavement. The metal rim is prefer. ably corrugated, as shown, on the outer side to prevent slip. Since the rubber partis proau tected and almost all the wear is on metal parts, the life of the wheel is correspondingly engthened. 'I

1. A vehicle-wheel having a iiellyl and aresilient ring thereon, and an outer rim which forms an inclosing casing for said ring and extends inwardl on each side to lap the edges of the telly', an a spring drivingl connection hetweenthe bdy of the wheel and the said inwardly-extending portion of the rim, allowing the latter to yield to tan ential strain, said connection boing indepen ent of the resilient member.

2. A vehicle-wheel having an outer rim with inwardly-extending slots therebetween, a res ient supporting member under the rim, permitting it to yiel l radially, and cross-bars secured tothe wheel'- projections with'- 1 IIO and extending at their ends into the slots, to transmit the tangential strain.

3. A vehicle-Wheel having en outer rim With pairs of inwhilly-projecting lugs on opposite sides thereof, the lugs having slots tlierehetiveen, a resilient supportin member under the rim, permitting it to yiel radially, and spring cross bers connected to' the spokes of the Wheels andprojecting at their ends into the slots, to transmit the tangential strain. y

4. A vehiele-wheel having a felly with e concave face, st pneumatic tube thereon, en outer metal casing over the tube, formed of sections rigidly connected together, and I5 which laps the edges of the felly end has inwerdly-extending projections with slots therebetweernend spring cross-bars fastened FRANK NEWeoMB.
